Old Email goes to the old administrative group when replied to.

Exchange security
Microsoft Exchange
Activity: We have moved a client's Exch 2003 mailbox from one administrative group to another. We also moved the user object in AD to a different OU. The domain has not changed. The email address has stayed the same. What is occuring now is when people reply to emails received prior to the move, the email is routed to the old server and an NDR is generated. If you look at the properties of the email address in the mailbox, the email address field is blank, The display field has the canonical address with the old OU. New emails are fine and are replied to correctly. Has anyone ever experienced this problem? Any help will be appreciated. Thanks Donald

Thanks. We'll let you know when a new response is added.

As a short term fix it may be worth adding the LegacyDN attribute as an X500 address to the object in AD, replies to old mails should then be delivered.

    Hi there, This Michael, a Junior support techcian.I will try to provide you with this solution, because we at our company the administrators had to move the old exchange server from the south africa to USA.Prior to the move all the users pst files had reside on the D: partition so that when the script is run it might relocate the relevant pathlocation of the users settings. Please check whether the client point to the correct parent server And also try to reset the nickname and automatic completion cache. you just have to do the following: 1.Exit outlook 2.start Microsoft win Explorer 3.On tools menu,click folder options, and then click view tab 4.Untick the hide unknown file extensions tab 5.In the search companion, box, type*.NK2 in the files or folder 8 In the look in box, select your local hard disk drive 9. click search 10.right click the .nk2 file with the name of the profile you want to reset, and click Rename 11. Rename the file to profile to profile name.bak, and press Enter 12. Exit win Explorer 13.restart outlook I hope you're using WIn XP

    Thanks Zomike Adding an X500 address to the object in AD worked. Now all old emails are being routed to the right place. We first added the X500 to the new OU but then realized that the X500 had to point to the old OU. Now that we think about it, it make sense. Again thank you for your help. Donald
